4-Spoke Direct Mount for SRAM GXP Cranks
The 4 spoke sizes that are out of stock will be back in stock in later spring 2015 (roughly May). We are in the process of updating them with our patent pending Drop Stop tooth profile. Thanks for your patience!

These are Direct Mount chainrings for SRAM GXP crank. This will replace you existing chainring and spider, which is attached via 3 bolts on the back side of the spider near the spindle. You will use these same 3 bolts to attach the SDM ring.
SDM chainrings fit on SRAM cranksets with removable spiders: S2200, S2210, X9, X0, X01, XX1, X1 1400, Truvativ AKA Cranksets (GXP version), and newer S1400 (or X7) . If the crankarm and the spider are all made from the same piece of aluminum it is not removable.
Chainline is 50mm on all rings (on a GXP or BB30 long spindle crankset). All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum.
These can also be used on a BB30 / PF30 long spindle crankset -- the decision tree photo in the carousel will help you determine if you need this ring or the Short Spindle BB30. This SDM ring is dished in ~6mm, whereas the BB30 short spindle ring is flat.
Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring.
A T25 Torx wrench is required to remove the bolts that secure the the chainring or spider to the crankarm. An L-wrench works best since the crank spindle may contact a socket adapter and prevent it from engaging properly.
